Multi-lumen tamper tube

Abstract

The present technology relates generally to a method and device for closing percutaneous punctures, and more particularly to a multi-lumen tamper for such a device. A closure device for sealing a percutaneous puncture in a wall of a body passageway is disclosed, the closure device including a plug configured to engage a surface of the puncture; a toggle configured to engage an internal surface of the body passageway; an elongate filament configured to associate the plug with the toggle; a locking member configured to engage the plug; and a tamper comprising at least two lumens, wherein a first lumen of the at least two lumens is configured to deliver a pharmaceutical agent to the plug.

The invention claimed is: 
     
       1. A closure device for sealing a percutaneous puncture in a wall of a body passageway, the closure device comprising:
 a plug configured to engage a surface of the puncture; 
 a toggle configured to engage an internal surface of the body passageway; 
 an elongate filament coupled to the toggle and the plug configured to associate the plug with the toggle; 
 a locking member disposed along the elongate filament and configured to slide along the elongated filament to engage the plug; and 
 a tamper disposed on the elongate filament at a location that is proximal to the locking member, the tamper having a proximal end, a distal end spaced from the proximal end, a first lumen that extends from the proximal end to the distal end, and a second lumen that extends from the proximal end to the distal end, wherein the first lumen and the second lumens are sized such that the locking member is prevented from being pushed inside the first and second lumens when the tamper slides along the elongated filament to tamper the locking member against the plug. 
 
     
     
       2. The closure device of  claim 1 , wherein the tamper is a cylindrical tamper tube. 
     
     
       3. The closure device of  claim 1 , wherein the elongate filament extends through the first lumen, wherein the guidewire is configured to pass through the second lumen. 
     
     
       4. The closure of  claim 3 , wherein at least one of the first and second lumens is a channel that runs along an outer surface portion of the surface of the tamper. 
     
     
       5. The closure device of  claim 1 , wherein the tamper comprises four or more lumens. 
     
     
       6. The closure device of  claim 1 , wherein the plug is a resorbable collagen sponge or foam. 
     
     
       7. The closure device of  claim 1 , wherein the tamper comprises an access opening that is fluidically coupled to one of said first and second lumens. 
     
     
       8. The closure device of  claim 1 , further comprising a drug delivery member to deliver a pharmaceutical agent through a third lumen. 
     
     
       9. The closure device of  claim 8 , further comprising an extension tube connected through which the drug delivery member may deliver the pharmaceutical agent to the third lumen. 
     
     
       10. The closure device of  claim 1 , wherein the first lumen and the second lumen of the tamper are substantially parallel to each other. 
     
     
       11. The closure of device of  claim 1 , wherein a third lumen is configured to deliver a pharmaceutical agent to a desired location at the puncture. 
     
     
       12. The closure device of  claim 11 , wherein the third lumen is configured to deliver the pharmaceutical agent to a desired location on the plug. 
     
     
       13. The closure device of  claim 1 , wherein the plug includes a first plurality of holes and a second plurality of holes, wherein the elongate filament extends through the first plurality of holes, and the second plurality of holes are configured to receive a guide wire. 
     
     
       14. The closure device of  claim 1 , wherein the plug includes a first plurality of holes and a second plurality of holes, wherein the elongate filament extends through a) the first plurality of holes, b) a hole in the toggle, and c) the second plurality of holes to form a slidable knot adjacent to the locking member. 
     
     
       15. The closure device of  claim 1 , wherein the tamper includes a plurality of openings.
